摘要:
A fuel redistribution control for an internal combustion engine (12) having a fuel control computer (10) and fuel delivery means (14) for delivering fuel to the engine in response to electrical signals. A signal generator (16) generating first signals indicative of the incremental rotational velocity of the engine's output member resulting from the torque impulses imparted to the output member by the individual cylinders, averaging means (18) for generating from said first signal an average rotational velocity signal, a circuit (20) for generating a difference signal indicative of the difference between said first signals and said average rotational velocity signal, integrator means (22) for individually accumulating said difference signals to generate a correction signal for each cylinder, means for averaging said correction signal (26) to generate an average correction signal, means for summing (28) said correction signal with the base fuel quantity signals generated by the fuel control computerto generate intermediate fuel quantity signals, and means for summing (30) the correction signals to said intermediate fuel quantity signal to generate a corrected fuel quantity signal activating the fuel delivery means (14) to deliver a quantity of fuel to each cylinder tending to equalize the contribution of each cylinder to the total output torque of the engine.
摘要:
A fuel distribution control for the fuel control system of an internal combustion engine (12) having a fuel control computer (10) generating fuel delivery signals indicative of the engines fuel requirements, means for delivering fuel (14) to the engine in response to said fuel delivery signals and means for generating amplitude signals (16) indicative of the magnitudes of the torque impulses generated by the individual cylinders, the fuel distribution control comprising means for correcting the amplitude signals (18) as a function of the cylinders position along the engine's crankshaft and engine speed, means for generating an average amplitude signal (20) for each cylinder, means for gnerating an individual difference signal (22) for each cylinder indicative of the difference between the average amplitude signal for the individual cylinders and the average amplitude of all the cylinders, means (26, 28) for generating a fuel correction for each individual cylinder from said difference signals, and means for summing (30) the fuel correction signal with the fuel delivery to generate a corrected fuel delivery signal operative to equalize the contribution of each cylinder to the total output torque of the engine.
